- New option, noconvert (-N, --noconvert) to completely stop
the translation of files from DOS or Mac format (DLR).
- New functions wheck_writable_directory() and safe_tempnam()
to get around the tempnam warning. (DLR) Needs testing
to get around the tempnam warning. More improvements (DLR)
Still eeds testing.
- Added DOS and Mac format options to write file routine.
Changes to shortcut_init() and do_writeout().
- Removed stupid static definitions of toggles and shortcut

- search.c
do_replace(), findnextstr()
- Fixes for various search issues (Ken Tyler)
- winio.c:
do_cursorpos()
- Rewritten to show col place as well as charcter place, without
needing an entirely separate flag.
bottombars(), onekey()
- Make bottom list dynamic with screen size (Guus Sliepen & Chris).
